What needs to happen to get this over the finish line?

[Smrtnyk]

What needs to happen to get this over the finish line?

I guess @SimenB has some doubts about this?

[SimenB]

Main reason is that this will make it much worse for node 12 and 14, and it's really a bug in node

[vanstinator]

Can we make it an opt-in change with a cli flag? I'm happy to do the work and update the tests. With node 14 going EOL this fall more people are going to be looking to move to 16 (including us at Plex). A cli flag would make the move much less painful. When node fixes their bug we can remove the option from jest again when it makes sense

[SimenB]

I don't think we should add a config flag - if we do this we should just detect the version of node inline so people don't have to change anything.

Maybe you could change this to use semver and detect broken versions (>= 16.11.0 I guess?), and if not broken use current code? Sorta similar to https://github.com/facebook/jest/blob/7826a8f15be07b2634add73a50decf73086e5948/packages/test-utils/src/ConditionalTest.ts#L37

[vanstinator]

Sure, that approach works too. I'll open a fresh PR based on this one when I'm ready. Thanks for the quick brainstorm!

[phawxby]

Is there anything I can do to get this PR moving along again? We generally try to avoid falling too far behind even minor versions

[SimenB]

@phawxby nothing new since the last activity, feel free to fix: https://github.com/facebook/jest/pull/12205#discussion_r815307518

@phawxby nothing new since the last activity, feel free to fix: #12205 (comment)

As you noted in the thread above, the importModuleDynamically issue could be a different bug. Would a way to handle this be to accept this PR but with importModuleDynamically implemented with the memory leak as it's not a regression in performance, for many will be a significant improvement. The importModuleDynamically memory leak issue can then be tackled separately?

importModuleDynamically being implemented voids the improvement, so that doesn't help. Unless you're seeing that it does help?

Ah, I misunderstood your comment as the issue only occurs when importing esm from cjs, not in all scenarios. I'm going to have a dig around this afternoon and see if I can find anything but I'm not holding out much hope.

[phawxby]

A bit more digging and I've found this, which suggests this isn't going to be especially easy to fix. https://github.com/nodejs/node/issues/25424#issuecomment-770216256

Which then ties in with this. https://bugs.chromium.org/p/v8/issues/detail?id=12198

[SimenB]

Instead of using a patch, one thing that can be done is to extend the default jest-runtime and override _execModule. It can be passed as runtime in configuration (renamed from moduleLoader in Jest 28).

https://github.com/facebook/jest/blob/f43871e37f8bf6dbe292ad2e52f4781868c4731b/packages/jest-runner/src/runTest.ts#L117-L121

While _execModule is private (by convention), it's not literally private at runtime (i.e. using #), so overriding should be fine.

const {default: JestRuntime} = require('jest-runtime');

module.exports = class CompileFunctionRuntime extends JestRuntime {
  _execModule() {
    // do something
  }
};

This module could then be published as a workaround. Somewhat brittle as _execModule isn't public API, but less brittle than applying a patch 🙂

[blimmer]

@a88zach has published https://github.com/reside-eng/jest-runtime which does what @SimenB suggested in the last comment. This unblocked us from upgrading to Node > 16.10.

See https://github.com/facebook/jest/issues/11956#issuecomment-1148857787.

[benjamingr]

Hey to understand does this issue manifest without any gc() calls?

[bvobart]

Same as @blimmer, I can confirm that https://github.com/reside-eng/jest-runtime (which is basically this PR as a workaround, using @SimenB's suggestion in this comment) significantly alleviates the memory leaking problems.

I have a medium-sized TypeScript project transformed with @swc/jest containing around 500 test cases that used to take up a massive 5.2 GB of RAM to run from start to finish, but now takes "only" 2.6 GB, effectively halving the RAM usage of Jest.

I've just tried the fixed runtime as well. Tests ended with 1.8GB of ram instead of 6GB.

[sunilsurana]

Hi @rthreei , Using side/jest-runtime we are seeing improvement in performance and memory usage. It is still 30% slower than node 16.10. Any clue if anything can be done. Without side/jest-runtime there is degradation for 100%

[Havunen]

In NodeJS v18.17.1 the heap increases from 118Mb to 5815MB and total runtime runInBand + logHeapUsage is 187sec using @side/jest-runtime the heap decreased to 5467 MB and total runtime runInBand + logHeapUsage is 165sec

:/

[SimenB]

Node landed a fix for vm.Script a few hours ago. Hopefully it'll be backported all the way to Node 18.

[Havunen]

NodeJs v20.8.0 running:

    "test": "cross-env NODE_OPTIONS=--max-old-space-size=8192 node --experimental-vm-modules ./node_modules/jest/bin/jest.js --config=jest.config.js --no-watchman --runInBand --logHeapUsage --ci",

  transform: {
    '\\.ts$': '@swc/jest',
    '\\.vue$': '<rootDir>/node_modules/vue2-swc-jest',
  },
  runtime: '@side/jest-runtime',

Bumps heap size from 125Mb to 5601 MB heap size (execution time 166 sec )

Removing runtime: '@side/jest-runtime', -setting:

Bumps heap size to 5778 MB ( execution time 178sec )

removing the runInBand and logHeapUsage with runtime: '@side/jest-runtime', 44sec without runtime: '@side/jest-runtime', 44.613sec

However not having --runInBand the memory usage is even more expensive and in dev ops cheap machines the computer is starwing...

[Havunen]

I'm starting to feel that there is some other memory leak issue as well, it feels like Jest keeps the test data in memory until the whole run is finished

[ximex]

@Havunen this fix (https://github.com/nodejs/node/pull/49950#event-10556827669) isn't in node 20.8.0. next week 20.9.0 should get released. maybe this fixes some of the memory problems

[Havunen]

@ximex is the fix available in any nightly / preview release? I would like to test if it solves this issue

[ximex]

I'm not the expert for this. but i think so if you try the todays nightly version

https://github.com/jestjs/jest/issues/11956#issuecomment-1741000133

I tried it but it does not seem to change anything? runtimeSupportsVmModules is true so it always sets the callback anyway?
